06-16-21

Adam Wierman, Professor of Computing and Mathematical Sciences; Director, Information Science and Technology, and Steven Low, Frank J. Gilloon Professor of Computing and Mathematical Sciences and Electrical Engineering, have received the SIGMETRICS Test of Time Award for their paper titled "Greening Geographical Load Balancing." The ACM SIGMETRICS Test of Time Award recognizes an influential performance evaluation paper whose impact is still felt 10-12 years after its initial publication. [Past winners]

Recording Brain Activity with Laser Light

06-07-21

Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, has demonstrated for the first time a new technology for imaging the human brain using laser light and ultrasonic sound waves. The technology, known as photoacoustic computerized tomography, or PACT, has been developed as a method for imaging tissues and organs. Now, Wang has made further improvements to the technology that make it so precise and sensitive that it can detect even minute changes in the amount of blood traveling through very tiny blood vessels as well as the oxygenation level of that blood.

Hrishika Basava Receives 2021 Henry Ford II Scholar Award

06-02-21

Hrishika Basava, advised by Ali Hajimiri, Bren Professor of Electrical Engineering and Medical Engineering; Co-Director, Space-Based Solar Power Project, is one of four recipients of the 2021 Henry Ford II Scholar Award. Hrishika is interested in many different aspects of electrical engineering, and specifically applications in robotics and aerospace. She does research in inverse design techniques for nanophotonics with Ali Hajimiri. Hrishika has also worked on the Caltech Racing electrical team and has done research on the explosion mechanism of supernovae at the Carnegie Observatories. At Caltech, she has particularly enjoyed taking hands-on project classes, as well as being a teaching assistant in electrical engineering courses. This summer, Hrishika will be interning at Nuro, a robotics company working on a self-driving car. After graduating she plans to pursue higher education and eventually work in the technology industry. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

JPL Designates Perseverance Rover’s Landing Site and Observation Point

04-12-21

The Jet Propulsion Laboratory has designated the Perseverance rover’s landing site as the Octavia E. Butler Landing and the rover’s observation point to record Ingenuity helicopter tests as the Van Zyl Overlook. Jakob van Zyl (MS ’83; PhD ‘86) joined JPL in 1986 and stayed for 33 years in various positions, including director for Astronomy, Physics and Space Technology. He taught at Caltech, as a senior faculty associate in electrical engineering and aerospace, for two decades. The Ingenuity helicopter was one of his last projects at the JPL. Van Zyl retired from the JPL in 2019 and passed away unexpectedly in August 2020. Octavia Butler lived just miles away from JPL; she was a pioneering author and one of the first Black female science fiction authors. Butler was the first to write about prominent Black characters in science fiction settings, using dystopias, time travel and other tropes. She was awarded both the Hugo and Nebula awards. In 1995, she became the first science fiction author to receive a MacArthur Foundation Fellowship. Butler passed away in 2006. [USA Today]

Astronomers Image Magnetic Fields at the Edge of M87's Black Hole

03-24-21

The Event Horizon Telescope (EHT) collaboration, which produced the first-ever image of a black hole, revealed a new view of the massive object at the center of the M87 galaxy: a picture of its polarized light. This is the first time astronomers have been able to measure polarization, a signature of magnetic fields, this close to the edge of a black hole. "We are now able to see a different dimension of the light circling the M87 black hole," says Katie Bouman, Assistant Professor of Computing and Mathematical Sciences, Electrical Engineering and Astronomy, Rosenberg Scholar, and co-coordinator of the EHT Imaging Working Group. "The image we reconstructed earlier showed us how bright the light was around the black hole shadow. This image is telling us about the direction of that light." [Caltech story]

Professor Bouman Featured in Inverse Magazine

03-10-21

Katie Bouman, Assistant Professor of Computing and Mathematical Sciences, Electrical Engineering and Astronomy; Rosenberg Scholar, was featured in Inverse Magazine as one of the astronomers who captured the first image of a black hole. In 2019, Bouman and a group of more than 200 astronomers from all over the world managed the inconceivable: They captured the first image of a black hole, rendering the invisible visible. "Ideally, to see a black hole, we would need a telescope the size of the entire Earth," says Bouman. "We had to come up with a computational telescope that size." [Inverse article]

New Insight into Nonlinear Optical Resonators Unlocks Door to Numerous Potential Applications

02-25-21

Devices known as optical parametric oscillators are among the widely used nonlinear resonators in optics; they are "nonlinear" in that there is light flowing into the system and light leaking out, but not at the same wavelengths. Though these oscillators are useful in a variety of applications, including in quantum optics experiments, the physics that underpins how their output wavelength, or spectrum, behaves is not well understood. "When you add strong nonlinearity to resonators, you enter what we call a 'rich physics regime,'" says Alireza Marandi, Assistant Professor of Electrical Engineering and Applied Physics. "'Rich' in physics terms usually means complicated and hard to use, but we need nonlinearities to create useful functionalities such as switching for computing." To be able to make full use of nonlinear optical resonators, researchers want to be able to understand and model the physics that underpin how they work. Marandi and his colleagues recently uncovered a potential way to engineer those rich physics, while discovering phase transitions in the light that is generated by the resonators. [Caltech story]
